How data is represented

Graphs display data points. To define graphs, you need to know how the data is represented. PocketBuilder organizes data into three components.

**Table 24-1: Components of a graph**
Component	Meaning
Series	A set of data points. Each set of related data points makes up one series. In Figure 24-1, there is a series for Stellar sales, another series for Cosmic sales, and another series for Galactic sales. Each series in a graph is distinguished by color, pattern, or symbol.
Categories	The major divisions of the data. Series data are divided into categories, which are often non-numeric. In Figure 24-1, the series are divided into four categories: Q1, Q2, Q3, and Q4. Categories represent values of the independent variable(s).
Values	The values for the data points (dependent variables).
